CLOSING APPARATUS FOR BOTTLES, 800.

SPECIFICATION forming part of Letters Patent No. 320,715, dated June 23,1885.

Application filed November 13, 1884.

To all whom it may concern.-

Be it known that I, HERMANN SPRIEGEL, a subject of the Emperor ofGermany, and a resident of Dantzic, in the Kingdom of Prussia, Germany,have invented certain Improvements in Bottle-Stoppers, of which thefollowing is a specification.

The object of my invention is to construct a bottle-stopper which shallbe capable of being easily and quickly applied, and yet securelyretained in place after it has been applied.

In the accompanying drawings, Figure 1 is a vertical section of myimprovement. Fig. 2 is a sectional plan on the line 1 2, and Fig. 3 is aside view of a bottle-neck without the stopper.

A is the bottle, which near the top is provided with the usual shoulder,a, and around the neck below the shoulder is attached a ring, 13, withsquare eyes b at diametricallyopposite points.

The stopper D, which consists of a disk. d, carrying a rubber face, iscombined with a sheet-metal cylinder, E, containing a spiral spring, F.One end of the spiral spring I prefer to secure to the closed top of thecyl-- inder E, while the other and lower end is secured to the diskwhich carries the stopper D.

Across the top of the cylinder E is secured a spring-clip, G, theopposite legs of which extend some little distance below the cylinder E,and have catches g of such a character that when the stopper is placedon the neck of the bottle these catches y can be passed through the eyesI) of the ring B and engage with the (No model.)

under side of these eyes to retain the parts in pressing on the stopperD to make a tight closure at the neck of the bottle.

In order to insure the retention of the stopper in place, I combine withthe abovedescribed devices a rubber or other suitable ring, H, aroundthe 'neck of the bottle below the ring B, and this ring H, when thestopper and its retaining-clip have been pressed into position and thecatches 9 have engaged with the eyes of the ring B, is pushed up behindthe catches g, to prevent their accidental withdrawal. On the otherhand, when it is desired to remove the stopper, the ring H is presseddownward, so as to leave the catches 9 free to be'disengaged.

In order to prevent the liquid in the bottle from acquiring a flavor ofindia-rubber from the stopper of the bottle, I prefer to line the faceof the latter with a disk of parchment paper, K.
